SVEGREGATING NESIT;

Application filed A pril 30, `19,25. Serial No. 26,959.

To all whom, it may concern:

Be it known that I, JOHN A. MooRn, a

citizen of the United States, andresident'ot Portland, county oit-'Multnomalnand State of Oregon, have invented certain new and useful Improvements in Segregating Nests,

` Asimple and inexpensive device composed `of few parts, which' isleasy toV manufacture and is readily 'assembledfand installed.

I4 attain my-object combining with a Y wall, or the like, having anv opening vtherein and separating an enclosure from an adjacent open space, sin-enclosed nest having an opening'adapte'd for yregistration nwith said wall opening, operablemeans normallysupporting said nest with its opening inA registration with said wall opening, said means being a'dapted'to sustain the weight of the nestwithout eifect,-butto partially-'rotate said )nestA slowly' .under additional weight thereby to place the opening of said nest out of registration with-said wall opening and instead exposing the opening of the nest to said enclosure only.

My object in restraining the operating of the rotation of my enclosed nest is to prevent scaring the hen off the nest by a. sudden movement of the latter.

My invention may be practically carried out in the manner illustrated in the accompanying drawings, in which:

Fig. 1 is a side elevation partly in section, showing a fence provided with an opening and to which fence my segregating nest is affixed, this figure showing the normal positions of the co-operating parts of my segregating nest. l

Fig. 2 is a. view similar to Fig. l, but in this instancevmy segregating nest has been rotated so as to place the opening thereof out of registration with the opening in the wall so that the hen will be confined in the space enclosed by the latter;

Fig. 3 is a plan section on the .line 3-3 of Fig. 2;

Fig. 4l is a sectional detail of the pivotal support for the. nest, the section being taken on the line 4-.4 of Fig. 1; and

Fig. 5 is a sectional detail ofthe cylinder and pump element of my segregating nest by which thesudden movement of the latter is restrained.

e represents. a fence bleh mayieensist of rails a and wire netting portonsb, asillustrated 11n Figs., l and 2. The wall is provded withanfopenng 0 and the enclosed nestcl is provided `.with a` singleopening e which normally registers with the opening c 1n the wall. Directly above the opening ein the wall is aflixed a bracket f and on the bracket is pivoted ay lever arm g, the Yfree end of which is yieldingly supported byy a spring Iz.. Devices are provided on said-arm Y by which the tensionor1 the springt. may be adjusted. These devices consist cfa slot g in said arm over which a'clip It is mounted. Said cli-p' /L isprovided with a lclamping screw-h? whichpasses through the slot g* lin the arm. A thumb .null k3 is providedon said clamping screw to fasten theclip to the arm when the spring is adjusted to the correct tension.

. A red i s11pp0rti11gthe.'nestfl, is Carried y by .fitting '7' Qn the erm g- ,Sedfitins .eenslsts 0f eimember 2'"Whie11 is pretally vsupp'erted-te. the; arm@ A beek y'-swivlsfn said member j and passes through an eye in the rod z'. Said rod d has a twisted spiral portion i which bears in a slotted aperture 7c formed' by a clip lc fastened to and forming a part of the bracket The twist in said rod z' thus causes said rod to be rotated when the rod is moved vertically. The downward movement of the rod will cause the partial rotation thereof'and therewith of the nest in one direction and the` return, upward, vvertical movement will cause its rotation in the reverse direction. The nest d is suspended from the pendent rod 1l and the spring h is adjusted so as to exactly support the weight of the nest and to holdy the lat-ter so positioned thatits opening e will registei with the opening c in the wall a'.

In order to prevent the sudden movement of the parts when a hen sets upon a nest I provide a cylinder filled with a fluid and provided with a piston m which reciprocates therein. The piston rod thereof extends through said piston m and is hollow for a portion of its length. An orifice oy extends through the wall of said piston rod above the piston and is proportioned relatively to the interval of time it shall take the. movewith the lever arm g through a bifurcated fitting p which is pivotally connected thereto.

In order to maintain the nest in vertical alinement at all times, I provide a bracket g below the opening in the wall and provide on the bottom of the nest cl a rod frwhich is journaled in the bracket Q and also slides therein.

The operation of my device is self evident from its description: When a hen enters the nest d and settles down to lay, thus remaining in the nest some considerable time, the weight of the hen will cause the said operating device slowly to rotate the nest until the opening e thereof is placed out of registration with the opening in the fence and permits the hen to leave the nest only in the space enclosed by said fence. As soon as the hen has left the nest the latter will assume its normal position. As mentioned, the movement of the nest is restrained tobe so gradual as to not frighten the hen. The slow movement of the nest also permits a non-laying fowl that has entered the nest, to leave it again if remaining in the nest only a short time.

I claim:

l. In a device of the character described, a bracket, a lever-arm mounted thereon, means connected to said lever-arm adapting the latter to sustain a predetermined weight, a vertically movable yrod pendent from said lever-arm, means for causing the partial rotation of said pendent rod during its vertical movement, an enclosed nest suspended from lsaid rod, said nest provided with an opening, means restraining the sudden movement ofl said lever-arm, whereby additional weight imposed upon said nest will cause .its partial rotation and thus relatively move its opening from one position to another, slowly.

2. Claim 1 distinguished in that said re straining means of the lever-arm consists of a cylinder filled with a Huid and a plunger therein provided with an Orifice and operable to displace said fluid from one end of the cylinder to the other.

3. In a device of the character described, a bracket, a lever-arm mounted thereon, means connected to said lever arm adapting the latter to sustain a predetermined weight, a rod pendent from said lever arm, means for causing the partial rotation of' said rod during its verticalv movement, an enclosed nest suspended fromV said pendent rod, said nest provided with an opening, and means restraining the sudde-n movement of said lever-arm, such means consisting of a cylinder filled with a fluid and plunger therein provided wth an orifice and operable to displace said fluid from one end of the cylinder to the other, whereby a weight imposed upon said nest will cause its partial rotation and thus relatively move its Vopeningv from one position to the other at a slow speed.
